May 13 (Reuters) - U.S. stocks opened higher on Wednesday as data suggested that the economy was not rebounding strongly enough for the Federal Reserve to raise interest rates before September.
U.S. retail sales were unchanged in April as households cut back on purchases of automobiles and other big-ticket items.
Import prices fell for a 10th straight month in April, while weekly applications for home mortgages were down as interest rates rose to the highest level since March.
“The data puts into question the Fed’s notion that the weak first-quarter data was transitory,” said Adam Sarhan, chief executive of Sarhan Capital in New York.
The Fed has said it will raise rates only when data points to a strengthening economy. Growth in the first-quarter slowed to a crawl as a strong dollar, harsh winter and a steep fall in oil prices hurt profits and discouraged consumers from spending.
Seven of the 10 major S&P 500 sectors were higher, led by the technology index, which rose 0.9 percent.

U.S. stocks closed down for the second straight day on Tuesday amid a global bond rout.
Macy’s fell 2.3 percent to $63.81, while Ralph Lauren was down 1.8 percent at $130.66 after results.
Shares of pipeline company Williams Partners LP jumped 22 percent to $57.87 after Williams Cos said it would buy its affiliate for about $13.8 billion.
